This part of IEC 61326 specifies requirements for immunity and emissions regarding electromagnetic
compatibility (EMC) for electrical equipment, operating from a supply or battery of
less than 1 000 V AC or 1 500 V DC or from the circuit being measured. Equipment intended
for professional, industrial-process, industrial-manufacturing and educational use is covered
by this part. It includes equipment and computing devices for
– measurement and test;
– control;
– LABORATORY use;
– accessories intended for use with the above (such as sample handling equipment),
intended to be used in industrial and non-industrial locations.
Computing devices and assemblies and similar equipment within the scope of information
technology equipment (ITE) and complying with applicable ITE EMC standards can be used in
systems within the scope of this part of IEC 61326 without additional testing, if they are
suitable for the intended electromagnetic environment.
It is generally considered that this product family standard takes precedence over the
corresponding generic EMC standards.
The following equipment is covered by this document.
a) Electrical measurement and test equipment
This is equipment which, by electrical means, measures, indicates or records one or more
electrical or non-electrical quantities, also non-measuring equipment such as signal
generators, measurement standards, power supplies and transducers.
b) Electrical control equipment
This is equipment which controls one or more output quantities to specific values, with
each value determined by manual settings, by local or remote programming, or by one or
more input variables. This includes industrial process measurement and control (IPMC)
equipment, which consists of devices such as:
– process controllers and regulators;
– programmable controllers;
– power supply units for equipment and systems (centralized or dedicated);
– analogue/digital indicators and recorders;
– process instrumentation;
– transducers, positioners, intelligent actuators, etc.
c) Electrical LABORATORY equipment, including In Vitro Diagnostic (IVD) medical equipment
This is equipment used to prepare or analyse materials, or measure, indicate or monitor
physical quantities. This equipment might also be used in areas other than laboratories.
d) Equipment a), b) or c) as above when being equipped with components having radio
functionality, for example for wireless communication.
Equipment within the scope of this document might be operated in different electromagnetic
environments; depending on the electromagnetic environment different emission and immunity
test requirements are applicable.
This document considers three types of electromagnetic environments:
• BASIC ELECTROMAGNETIC ENVIRONMENT;
• INDUSTRIAL ELECTROMAGNETIC ENVIRONMENT;
• CONTROLLED ELECTROMAGNETIC ENVIRONMENT.
Corresponding immunity test requirements are described in Clause 6.
In terms of emission requirements, equipment shall be classified in Class A or Class B
equipment, as per the requirements and procedure of CISPR 11. The corresponding emission
requirements are described in Clause 7.
The specified emission and immunity requirements aim at achieving electromagnetic
compatibility between equipment covered in this document and other equipment that might
operate at locations with electromagnetic environments considered in this document.
Guidance for an assessment concerning the risk for achieving EMC is given in Annex B.

FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
in the subject dealt with may participate in this preparatory work. International, governmental and non-
governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
with the International Organization for Standardization (ISO) in accordance with conditions determined by
agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence
between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of
patent rights. IEC shall not be held responsible for identifying any or all such patent rights.
International Standard IEC 61326-1 has been prepared by subcommittee 65A: System
aspects, of IEC technical committee 65: Industrial-process measurement, control and
automation.
This third edition cancels and replaces the second edition, published in 2012. This edition
constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous
edition:
– the immunity test levels and performance criteria have been reviewed;
– requirements for portable test and measurement equipment have been clarified and
amended;

INTRODUCTION
Instruments and equipment within the scope of this document may often be geographically
widespread and hence operate under a wide range of environmental conditions.
The limitation of undesired electromagnetic emissions ensures that no other equipment
installed nearby is unduly influenced by the equipment under consideration. The limits are
more or less specified by, and therefore taken from, IEC and International Special Committee
on Radio Interference (CISPR) publications.
However, the equipment should function without undue degradation in an electromagnetic
environment typical for the locations where it is intended to be operated. In this respect, the
document specifies three different types of electromagnetic environment and the levels for
immunity. More detailed information about issues related to electromagnetic environments are
given in IEC TR 61000-2-5. Special risks, involving for example nearby or direct lightning
strikes, circuit-breaking, or exceptionally high electromagnetic radiation in close proximity, are
not covered.
Complex electric and/or electronic systems should require EMC planning in all phases of their
design and installation, taking into consideration the electromagnetic environment, any
special requirements, and the severity of failures.
This part of IEC 61326 specifies the EMC requirements that are generally applicable to all
equipment within its scope. For certain types of equipment, these requirements will be
supplemented or modified by the special requirements of one, or more than one, particular
part IEC 61326-2 (all parts). These should be read in conjunction with the IEC 61326-1
requirements.

This is equipment which, by electrical means, measures, indicates or records one or more
electrical or non-electrical quantities, also non-measuring equipment such as signal
generators, measurement standards, power supplies and transducers.
b) Electrical control equipment
This is equipment which controls one or more output quantities to specific values, with
each value determined by manual settings, by local or remote programming, or by one or
more input variables. This includes industrial process measurement and control (IPMC)
equipment, which consists of devices such as:
– process controllers and regulators;
– programmable controllers;
– power supply units for equipment and systems (centralized or dedicated);
– analogue/digital indicators and recorders;
– process instrumentation;
– transducers, positioners, intelligent actuators, etc.

d) Equipment a), b) or c) as above when being equipped with components having radio
functionality, for example for wireless communication.
Equipment within the scope of this document might be operated in different electromagnetic
environments; depending on the electromagnetic environment different emission and immunity
test requirements are applicable.
This document considers three types of electromagnetic environments:
• BASIC ELECTROMAGNETIC ENVIRONMENT;
• INDUSTRIAL ELECTROMAGNETIC ENVIRONMENT;
• CONTROLLED ELECTROMAGNETIC ENVIRONMENT.
Corresponding immunity test requirements are described in Clause 6.
In terms of emission requirements, equipment shall be classified in Class A or Class B
equipment, as per the requirements and procedure of CISPR 11. The corresponding emission
requirements are described in Clause 7.
The specified emission and immunity requirements aim at achieving electromagnetic
compatibility between equipment covered in this document and other equipment that might
operate at locations with electromagnetic environments considered in this document.
Guidance for an assessment concerning the risk for achieving EMC is given in Annex B.

70 FOREWORD
71 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
72 all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
73 international co-operation on all questions concerning standardization in the electrical and electronic fields. To
74 this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
75 Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
76 Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
77 in the subject dealt with may participate in this preparatory work. International, governmental and non-
78 governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
79 with the International Organization for Standardization (ISO) in accordance with conditions determined by
80 agreement between the two organizations.
81 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
82 consensus of opinion on the relevant subjects since each technical committee has representation from all
83 interested IEC National Committees.
84 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
85 Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
86 Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
87 misinterpretation by any end user.
88 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
89 transparently to the maximum extent possible in their national and regional publications. Any divergence
90 between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
91 the latter.
92 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
93 assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
94 services carried out by independent certification bodies.
95 6) All users should ensure that they have the latest edition of this publication.
96 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
97 members of its technical committees and IEC National Committees for any personal injury, property damage or
98 other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
99 expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
100 Publications.
101 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
102 indispensable for the correct application of this publication.
103 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of
104 patent rights. IEC shall not be held responsible for identifying any or all such patent rights.
105 International Standard IEC 61326-1 has been prepared by subcommittee 65A: System
106 aspects, of IEC technical committee 65: Industrial-process measurement, control and
107 automation.
108 This third edition cancels and replaces the second edition, published in 2012. This edition
109 constitutes a technical revision.
110 The significant technical changes with respect to the previous edition are as follows:
111 – the immunity test levels and performance criteria have been reviewed;
112 – requirements for PORTABLE TEST AND MEASUREMENT EQUIPMENT have been clarified and
113 amended;
114 – the description of the electromagnetic environments has been improved.

136 INTRODUCTION
137 Instruments and equipment within the scope of this standard may often be geographically
138 widespread and hence operate under a wide range of environmental conditions.
139 The limitation of undesired electromagnetic emissions ensures that no other equipment,
140 installed nearby, is unduly influenced by the equipment under consideration. The limits are
141 more or less specified by, and therefore taken from, IEC and International Special Committee
142 on Radio Interference (CISPR) publications.
143 However, the equipment should function without undue degradation in an electromagnetic
144 environment typical for the locations where it is intended to be operated. In this respect the
145 standard specifies three different types of electromagnetic environment and the levels for
146 immunity. More detailed information about issues related to electromagnetic environments are
147 given in IEC 61000-2-5. Special risks, involving for example nearby or direct lightning strikes,
148 circuit-breaking, or exceptionally high electromagnetic radiation in close proximity, are not
149 covered.
150 Complex electric and/or electronic systems should require EMC planning in all phases of their
151 design and installation, taking into consideration the electromagnetic environment, any
152 special requirements, and the severity of failures.
153 This part of IEC 61326 specifies the EMC requirements that are generally applicable to all
154 equipment within its scope. For certain types of equipment, these requirements will be
155 supplemented or modified by the special requirements of one, or more than one, particular
156 part within IEC 61326-2 series. These should be read in conjunction with the IEC 61326-1
157 requirements.

167
168 1 Scope
169 This part of IEC 61326 specifies requirements for immunity and emissions regarding electro-
170 magnetic compatibility (EMC) for electrical equipment, operating from a supply or battery of
171 less than 1 000 V AC or 1 500 V DC or from the circuit being measured. Equipment intended
172 for professional, industrial-process, industrial-manufacturing and educational use is covered
173 by this part. It includes equipment and computing devices for
174 – measurement and test;
175 – control;
176 – LABORATORY use;
177 – accessories intended for use with the above (such as sample handling equipment),
178 intended to be used in industrial and non-industrial locations.
179 Computing devices and assemblies and similar equipment within the scope of Information
180 Technology Equipment (ITE) and complying with applicable ITE EMC standards may be used
181 in systems within the scope of this part of IEC 61326 without additional testing, if they are
182 suitable for the intended electromagnetic environment.
183 It is generally considered that this product family standard takes precedence over the
184 corresponding generic EMC standards.
185 The following equipment is covered by this standard.
186 a) Electrical measurement and test equipment
187 This is equipment which, by electrical means, measures, indicates or records one or more
188 electrical or non-electrical quantities, also non-measuring equipment such as signal
189 generators, measurement standards, power supplies and transducers.
190 b) Electrical control equipment
191 This is equipment which controls one or more output quantities to specific values, with
192 each value determined by manual settings, by local or remote programming, or by one or
193 more input variables. This includes Industrial Process Measurement and Control (IPMC)
194 equipment, which consists of devices such as:
195 – process controllers and regulators;
196 – programmable controllers;
197 – power supply units for equipment and systems (centralized or dedicated);
198 – analogue/digital indicators and recorders;
199 – process instrumentation;
200 – transducers, positioners, intelligent actuators, etc.

202 c) Electrical LABORATORY equipment, including In Vitro Diagnostic (IVD) equipment
203 This is equipment used to prepare or analyse materials, or measure, indicate or monitor
204 physical quantities. This equipment might also be used in areas other than laboratories.
205 d) Equipment a), b) or c) as above when being equipped with components having radio
206 functionality, for example for wireless communication.
207 Equipment within the scope of this standard might be operated in different electromagnetic
208 environments; depending on the electromagnetic environment different emission and immunity
209 test requirements are applicable.
210 This standard considers three types of electromagnetic environments:
211 • basic electromagnetic environment;
212 • industrial electromagnetic environment;
213 • controlled electromagnetic environment.
214 Corresponding immunity test requirements are described in Clause 6.
215 In terms of emission requirements, equipment shall be classified in Class A or Class B
216 equipment, as per the requirements and procedure of CISPR 11. The corresponding emission
217 requirements are described in Clause 7.
218 The specified emission and immunity requirements aim at achieving electromagnetic
219 compatibility between equipment covered in this standard and other equipment that might
220 operate at locations with electromagnetic environments considered in this standard. Guidance
221 for an assessment concerning the risk for achieving EMC is given in Annex B.
